Description

Technical Field

[0001] This application relates to the field of anti-seepage wall technology in water conservancy projects, and in particular to a horizontal demountable anti-seepage wall joint pipe assembly and a joint pipe operation and monitoring system. Background Technology

[0002] The construction of joints in the trench sections of a cutoff wall is a crucial and challenging aspect of concrete cutoff wall construction, as its quality directly impacts the effectiveness of the cutoff wall. The joint pipe method is currently a reliable technique for joint treatment in concrete cutoff walls. Specifically, a joint pipe, with a depth equivalent to the trench hole, is lowered into the trench using a crane and fixed in place to support the first stage of concrete to be poured. After the concrete in the trench has hardened to the predetermined strength, the joint pipe is slowly pulled out using specialized lifting equipment, forming a stable joint hole to facilitate the connection of the second stage of concrete.

[0003] The core difficulty and key technology of the joint pipe method construction lies in controlling the timing of joint pipe extraction: if extraction is too early, the concrete has not yet reached the predetermined strength, which can easily lead to shrinkage or collapse of the joint hole; if extraction is too late, the adhesion and friction between the joint pipe surface and the concrete will increase significantly, making extraction difficult. Especially for ultra-deep cutoff walls with a depth exceeding 100m, the extraction force required for joint pipe extraction is extremely large, requiring heavy-duty extraction equipment, and the joint pipe is easily jammed by the concrete and cannot be pulled out; if the pipe is forcibly pulled out, it will also cause damage to the concrete at the joint and equipment, leading to construction accidents.

[0004] Existing joint pipes have significant drawbacks in cutoff wall construction: the joint pipe supports continuously poured concrete, the bottom concrete has already solidified while the newly poured top concrete has not yet initially set, and the setting strength of the concrete near the bottom of the joint pipe is difficult to accurately control. This makes it impossible to precisely control the timing of joint pipe extraction, which can easily lead to accidents such as borehole collapse and pipe casting during construction. Therefore, in actual construction, methods such as controlling the concrete pouring speed, controlling the extraction speed, and keeping the joint pipe moving slowly are commonly used. By estimating the setting time, the joint pipe is extracted only after the concrete at the bottom has set to the predetermined strength, and large extraction equipment is used to ensure sufficient extraction force. This construction method not only seriously reduces construction efficiency and affects the construction quality of the cutoff wall joints, but also requires large extraction equipment, indicating a significant need for technical improvement, especially in the construction of ultra-deep cutoff walls. Summary of the Invention

[0006] This application also provides a joint pipe operation and monitoring system.

[0007] According to an embodiment of the first aspect of this application, a horizontal stripping anti-seepage wall joint pipe assembly is installed in an anti-seepage wall trench to support the concrete in the anti-seepage wall trench and form an anti-seepage wall joint; the horizontal stripping anti-seepage wall joint pipe assembly includes at least one joint pipe section, and when the number of joint pipe sections is greater than or equal to two, each joint pipe section is connected end to end along the height direction. The connector tube includes: Inner support cylinder; The movable segment is movably installed on the inner support cylinder; the movable segment has a supporting state and a demolding state. When the movable segment is in the supporting state, it supports the concrete in the anti-seepage wall trench. When the movable segment is in the demolding state, the movable segment separates from the concrete. A drive unit, mounted on the inner support cylinder, has a receiving cavity; fluid can be injected into the receiving cavity to change the volume of the drive unit, and the change in the volume of the drive unit drives the movable tube segment to move.

[0008] According to one embodiment of this application, the inner support cylinder is provided with a through hole extending in the horizontal direction; The connector tube also includes: A force transmission rod is inserted into the through hole, and its first end is connected to the inner wall of the movable tube segment to constrain the movement direction of the movable tube segment. A force transmission plate is connected to the second end of the force transmission rod, and a first installation space is formed between the force transmission plate and the inner support cylinder; The number of driving components is at least one, including a first driving component; the first driving component is disposed at the first mounting space, and the volume of the first driving component changes to drive the force transmission plate to move.

[0009] According to one embodiment of this application, the driving element further includes a second driving element; A second mounting space is formed between the movable tube segment and the inner support cylinder. The second driving member is installed at the second mounting space, and the volume of the second driving member changes to drive the movable tube segment to move.

[0010] According to one embodiment of this application, the connector tube further includes: A pressure sensor is connected to the receiving cavity of the second drive component through a connecting pipe to monitor the fluid pressure inside the second drive component, and to determine the degree of concrete solidification and the demolding time based on the monitored changes in fluid pressure over time.

[0011] According to one embodiment of this application, the connector tube further includes a fixed tube segment, which is fixedly connected to the inner support cylinder, and the fixed tube segment and the movable tube segment are located on opposite sides of the inner support cylinder in the radial direction of the inner support cylinder.

[0012] According to one embodiment of this application, the central angle of the fixed tube segment is 100° to 170°, and the central angle of the movable tube segment is 180° to 185°.

[0013] According to one embodiment of this application, the connector tube further includes a connecting sleeve, the two ends of which are respectively connected to the inner wall surface of the movable tube segment and the inner support cylinder to constrain the movement direction of the movable tube segment.

[0014] According to one embodiment of this application, the connector tube further includes a reset member that provides a reset force to bring the movable tube sheet toward the demolded state.

[0015] According to one embodiment of this application, along the height direction of the connector tube, one end of the inner support cylinder is provided with a socket and the other end is provided with a spigot, and adjacent connector tubes are fitted through the socket and the spigot.

[0016] A pipe fitting operation and monitoring system according to a second aspect of this application includes: The aforementioned horizontal de-modulation seepage barrier wall joint pipe assembly; A water tank, connected to the receiving cavity of the drive unit, is used to provide pressurized liquid; The control and monitoring equipment controls the amount of pressurized liquid injected into the drive component and acquires the pressure data within the drive component.

[0017] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects: The horizontal stripping cutoff wall joint pipe assembly of this application includes a joint pipe comprising a movable segment that can move radially. Once the concrete has hardened to a certain strength, the joint pipe can be separated from the concrete by the radial movement of the movable segment. This method of separation by radial relative movement of the joint pipe and concrete significantly reduces the pulling force required compared to traditional axial pipe pulling, and lowers the precision requirements for the timing of pulling the joint pipe away from the concrete. It also avoids the disturbance and damage to the wall joint caused by the traditional joint pipe pulling process, thus improving the overall quality of the cutoff wall. The movable segment is driven by a variable-volume drive component. The drive component's accommodating cavity changes its own volume by injecting fluid, thereby squeezing and driving the movable segment to move. The driving method is simple and reliable. Furthermore, the horizontal stripping cutoff wall joint pipe assembly includes one or more joint pipe sections arranged along the height direction. When the joint pipe is set to multiple sections, the process of separating each joint pipe from the concrete of its corresponding layer can be realized individually, without constantly maintaining the pipe pulling state. Therefore, the concrete pouring speed can be significantly increased, and the construction efficiency of the cutoff wall can be greatly improved.

[0033] A horizontal demounting anti-seepage wall joint pipe assembly according to an embodiment of the first aspect of this application, such as... Figures 1 to 3As shown, the horizontal demolding cutoff wall joint pipe assembly is installed in the cutoff wall trench to support the concrete in the trench and form a cutoff wall joint. The horizontal demolding cutoff wall joint pipe assembly includes at least one joint pipe 1, and when the number of joint pipes 1 is greater than or equal to two, the joint pipes 1 are connected end to end along the height direction. The joint pipe 1 includes an inner support cylinder 11, a movable pipe segment 12, and a driving component 13. The movable pipe segment 12 is movably installed on the inner support cylinder 11. The movable pipe segment 12 has a supporting state and a demolding state. When the movable pipe segment 12 is in the supporting state, it supports the concrete in the cutoff wall trench. When the movable pipe segment 12 is in the demolding state, it separates from the concrete. The driving component 13 is installed on the inner support cylinder 11 and has a receiving cavity 131. Fluid can be injected into the receiving cavity 131 to change the volume of the driving component 13. The change in the volume of the driving component 13 drives the movable pipe segment 12 to move. The phrase "the volume change of the driving component 13 drives the movement of the movable tube segment 12" can be achieved by injecting fluid into the receiving cavity 131 of the driving component 13, causing the volume of the driving component 13 to increase and compress the movable tube segment 12 to move. The driving component 13 can be a water bladder, a liquid bladder, an oil bladder, or an air bladder, etc. The fluid injected into the receiving cavity 131 can be water, oil, or other forms of liquid, or compressed air. For ease of description, the following description uses the example of "the driving component 13 using a water bladder and the fluid using water."

[0034] The horizontal demolding joint pipe assembly for the anti-seepage wall is used within the anti-seepage wall trench to support concrete and form the anti-seepage wall joint. The joint pipe 1 can be one or more sections, connected end-to-end along the height direction when multiple sections are used, adapting to trenches of different depths. The inner support cylinder 11 of the joint pipe 1 is the core load-bearing structure, providing an installation foundation for the movable segment 12 and the driving component 13. The movable segment 12 moves radially along the inner support cylinder 11. In the supporting state, it adheres to the concrete to form a supporting surface, ensuring the quality of the joint forming; in the demolding state, it shrinks radially and separates from the concrete, achieving the demolding action. The driving component 13 can be installed on the inner support cylinder 11. After liquid is injected into the receiving cavity 131, its volume changes, and the thrust generated by the volume expansion drives the movable segment 12 to move radially. This liquid-driven method allows for smooth force transmission.

[0035] Separation from concrete is achieved through the radial movement of the movable pipe segment 12. This radial relative movement significantly reduces the force required for separation, lowers the power requirements of the pulling equipment, and makes construction more convenient. Traditional axial pipe pulling requires high precision in timing, but this structure relaxes this requirement, reducing construction problems caused by timing deviations. The separation process causes minimal disturbance to the wall joints, preventing cracks and damage at the joints and ensuring the overall seepage prevention performance and structural strength of the cutoff wall. The liquid-driven drive component 13 has a simple structure, stable force transmission, and can precisely control the movement amplitude of the movable pipe segment 12, adapting to the demolding requirements of concrete with different setting strengths. The multi-section joint pipe 1 can independently complete the separation of the corresponding concrete layer without continuously maintaining the pulling state, accelerating the concrete pouring rhythm and improving construction efficiency. The drive component 13 is driven by changes in liquid volume, adapting to complex construction environments, is not easily affected by impurities in the trench, and has high operational reliability.

[0036] According to one embodiment of this application, such as Figures 1 to 3 As shown, the inner support cylinder 11 is provided with a through hole 115 extending in the horizontal direction; the connector pipe 1 also includes a force transmission rod 141 and a force transmission plate 142. The force transmission rod 141 passes through the through hole 115, and its first end is connected to the inner side wall of the movable tube 12 to constrain the movement direction of the movable tube 12; the force transmission plate 142 is connected to the second end of the force transmission rod 141, and a first mounting space 143 is formed between the force transmission plate 142 and the inner support cylinder 11; the number of driving members 13 is at least one, including a first driving member 132; the first driving member 132 is disposed at the first mounting space 143, and the volume change of the first driving member 132 drives the force transmission plate 142 to move.

[0037] The first driving component 132 expands in volume when water is injected, which can drive the movable tube 12 to move and achieve demolding.

[0038] The horizontal through hole 115 on the inner support cylinder 11 provides an installation and guiding channel for the force transmission rod 141. After the force transmission rod 141 passes through the through hole 115, its first end is fixedly connected to the inner wall of the movable tube 12, constraining the movable tube 12 to move only radially, thus preventing it from shifting or jamming during the force application process. The second end of the force transmission rod 141 is fixedly connected to the force transmission plate 142. The first installation space 143 between the force transmission plate 142 and the inner support cylinder 11 provides a suitable installation space for the first driving component 132, ensuring that the first driving component 132 is reasonably laid out and does not interfere with other structures. The first driving component 132 changes its volume by injecting liquid into the receiving cavity 131. When the volume expands, it applies a thrust to the force transmission plate 142. The thrust is transmitted to the movable tube 12 in sequence through the force transmission plate 142 and the force transmission rod 141, driving the movable tube 12 to move radially, forming a complete force transmission chain.

[0039] The cooperation between the force transmission rod 141 and the horizontal through hole 115 can precisely constrain the movement trajectory of the movable tube segment 12, preventing the movable tube segment 12 from tilting due to uneven force, preventing local jamming with the concrete, and improving the smoothness and accuracy of the demolding action. The force transmission plate 142 increases the contact area between the driving component 13 and the force transmission structure, so that the driving force is evenly distributed to the force transmission rod 141, avoiding local force concentration that could cause deformation or breakage of the force transmission rod 141, and extending the overall service life of the component. The first driving component 132 indirectly drives the movable tube segment 12 through the force transmission structure, without the need for a direct rigid connection with the movable tube segment 12, reducing the direct impact of the concrete lateral pressure on the driving component 13, reducing the probability of damage to the driving component 13, and improving operational reliability. The setting of the force transmission chain makes the installation position of the driving component 13 more flexible, avoiding the key stress area inside the movable tube segment 12, adapting to different specifications of movable tube segments 12, while strengthening the rationality of radial demolding force, continuing the advantages of radial movement demolding in reducing force and wall disturbance.

[0040] In some embodiments, a lubricating layer may be added to the inner wall of the through hole 115 to reduce the friction of the force transmission rod 141 during movement. The size of the force transmission plate 142 may be slightly larger than the cross-section of the first driving member 132 to ensure uniform transmission of driving force. The two ends of the first driving member 132 are respectively attached to the force transmission plate 142 and the inner support cylinder 11 to ensure that the thrust is transmitted without loss.

[0041] According to one embodiment of this application, such as Figures 1 to 3 As shown, the driving component 13 also includes a second driving component 135; a second mounting space 144 is formed between the movable tube 12 and the inner support cylinder 11, and the second driving component 135 is installed at the second mounting space 144. The volume of the second driving component 135 changes to drive the movable tube 12 to move.

[0042] The second driving component 135 and the first driving component 132 work together, corresponding to the supported state and the demolding state of the movable tube segment 12, respectively. A second mounting space 144 is formed between the inner side of the movable tube segment 12 and the outer wall of the inner support cylinder 11, providing installation space for the second driving component 135, ensuring a compact layout and not interfering with the force transmission structure. The second driving component 135 expands by injecting liquid into the receiving cavity 131, applying a radially outward thrust to the movable tube segment 12, tightly pressing the movable tube segment 12 against the concrete surface, maintaining the supported state to ensure the quality of the joint molding. The first driving component 132 is located in the first mounting space 143 between the force transmission plate 142 and the inner support cylinder 11. During liquid expansion, it pushes the force transmission plate 142, which, via the force transmission rod 141, drives the movable tube segment 12 to move radially inward, achieving demolding.

[0043] The second drive component 135 is attached to the inner support cylinder 11 and the movable tube segment 12 at both ends to ensure that the supporting force is transmitted evenly; the dual drive components 13 are independently controlled by liquid and can adjust the pressure separately to adapt to different stress requirements after concrete pouring and setting, continuing the core logic of radial movement.

[0044] The dual drive components have clearly defined functions. The second drive component 135 provides precise, continuous, and stable support force, ensuring a tight fit between the movable segment 12 and the concrete. This prevents segment displacement due to lateral pressure during pouring and guarantees the forming accuracy of the anti-seepage wall joint. The first drive component 132 is specifically responsible for demolding, separating the movable segment 12 by pulling it radially inward, reducing damage to the wall joint. Both drive components 13 work independently and can flexibly switch states according to the concrete setting progress. The support force of the second drive component 135 can be precisely adjusted through injection pressure to adapt to changes in lateral pressure at different pouring stages. The first drive component 132 focuses on demolding to optimize power parameters. The combination of the two enhances the adaptability of the component to complex construction conditions and improves overall operational stability. It should be noted that the aforementioned "the number of drive components 13 is at least one" means "drive component 13 may include only the first drive component 132," and "dual drive components" means "drive component 13 includes both the first drive component 132 and the second drive component 135."

[0045] The first drive member 132 is provided with a connection port 133, which is connected to a first connection pipe 134; the second drive member 135 is provided with a connection port 136, which is connected to a second connection pipe 137, so as to inject pressurized liquid into the first drive member 132 and the second drive member 135.

[0046] According to one embodiment of this application, the connector pipe 1 further includes a pressure sensor (not shown in the figure). The pressure sensor is connected to the receiving cavity of the second drive member 135 through a connecting pipe (i.e., the second connecting pipe 137) to monitor the fluid pressure in the second drive member 135 and determine the degree of concrete solidification and demolding time based on the monitored fluid pressure changes over time.

[0047] One end of the connecting pipe (i.e., the second connecting pipe 137) is connected to the second driving component 135, and the other end is connected to a pressure sensor on the ground surface. The pressure sensor is integrated into the joint pipe operation and monitoring system. The pressure sensor is used to monitor the change of fluid pressure value inside the second driving component 135 over time. Based on the monitored fluid pressure value change curve over time, the degree of concrete solidification is determined. By accurately determining the degree of concrete solidification, the accurate timing for pipe removal can be determined.

[0048] In some embodiments, the first drive unit 132 may also be connected to a pressure sensor via a first connecting pipe 134 to synchronously monitor the fluid pressure within the first drive unit.

[0049] When the joint pipe is supported, the second drive component 135 injects liquid to expand and press against the movable pipe segment 12. The concrete side pressure is transmitted to the second drive component 135. The pressure sensor is located in the ground module of the joint pipe operation and monitoring system and collects pressure data in real time. During the concrete solidification process, the side pressure will change with the degree of solidification. The control and monitoring equipment receives the pressure data and analyzes the trend of change to determine the degree of concrete solidification.

[0050] For example, as the concrete gradually hardens, the overall compressive force of the concrete on the joint pipe assembly gradually decreases; the relationship between the lateral pressure of the concrete on the wall of joint pipe 1 and time is shown in the curve. Figure 7 As shown, the curve generally exhibits a trend of first rising and then falling: After the movable segment 12 is in the supported state, concrete gradually fills from the lower end of the joint pipe section. As the amount of concrete filling increases, the lateral pressure of more concrete on the joint pipe gradually increases. When the concrete reaches the top of the joint pipe section, it continues to fill to the next higher joint pipe section, further increasing the lateral pressure. When the combined effect of "gradual solidification of the lower layer of concrete" and "continued increase in concrete filling" reaches a critical value, the lateral pressure on the joint pipe section reaches its maximum. The effect of the subsequent upper layer of concrete on the lateral pressure of the joint pipe section gradually decreases, while the effect of gradual concrete solidification increases. This combined effect leads to a gradual decrease in the lateral pressure on the joint pipe section.

[0051] The pressure sensor, located in the surface module of the joint pipe operation and monitoring system, provides real-time feedback on internal pressure changes in the drive component 13. This directly reflects the lateral pressure changes during concrete solidification, providing a quantitative basis for judging the degree of solidification and reducing subjective biases from manual judgment. Accurate solidification level judgment allows for optimal demolding timing, preventing premature demolding leading to joint deformation or delayed demolding increasing demolding resistance. Pressure data can be used in conjunction with control and monitoring equipment to regulate the water injection volume of the drive component 13, dynamically matching the support force, demolding force, and concrete state. This improves the smoothness of the demolding action, further reducing disturbance to the wall joint and ensuring the overall quality of the anti-seepage wall.

[0052] According to one embodiment of this application, such as Figures 1 to 3 As shown, the connector tube 1 also includes a fixed tube segment 15, which is fixedly connected to the inner support cylinder 11. In the radial direction of the inner support cylinder 11, the fixed tube segment 15 and the movable tube segment 12 are located on opposite sides of the inner support cylinder 11.

[0053] Fixed segment 15 and movable segment 12 are arranged radially opposite to each other on the inner support cylinder 11. Fixed segment 15 can be fixed to the inner support cylinder 11 by fixed steel frame 163 to ensure reliable connection. In the supporting state, the second driving member 135 pushes the movable segment 12 against the concrete; in the demolding state, the first driving member 132 pulls the movable segment 12 radially retract. Fixed segment 15 always remains stationary and does not affect the separation of movable segment 12 from the concrete. It works in cooperation with movable segment 12 to complete the joint forming and demolding process.

[0054] The axial length of the fixed segment 15 can be the same as that of the movable segment 12.

[0055] The fixed tube segment 15 does not participate in the movement. The combination of static and dynamic design with the movable tube segment 12 not only retains the demolding flexibility of the movable tube segment 12, but also strengthens the overall structural strength of the inner support cylinder 11 through fixed support, avoiding deformation and damage of the inner support cylinder 11 due to long-term stress.

[0056] According to one embodiment of this application, the central angle of the fixed segment 15 is 100° to 170°, and the central angle of the movable segment 12 is 180° to 185°.

[0057] At the same time, sufficient distance should be ensured between the circumferential ends of the fixed tube segment 15 and the movable tube segment 12 to ensure that the movable tube segment 12 will not collide or interfere with the fixed tube segment 15 during the demolding process.

[0058] For example, the central angle corresponding to the movable segment 12 can be 180°, and the central angle corresponding to the fixed segment 15 can be 170°.

[0059] According to one embodiment of this application, such as Figures 1 to 3 As shown, the connector tube 1 also includes a connecting sleeve 161, the two ends of which are connected to the inner wall surface of the movable tube 12 and the inner support cylinder 11, respectively, to constrain the movement direction of the movable tube 12.

[0060] The connecting sleeve 161 serves as an auxiliary guide structure for the movable segment 12. Its two ends are fixedly connected to the inner wall of the movable segment 12 and the inner support cylinder 11, respectively, forming a guiding constraint. It adapts to the radial movement trajectory of the movable segment 12 and, together with the force transmission rod 141, constitutes a dual guiding system, preventing the movable segment 12 from shifting or twisting when pushed by the second driving member 135 or pulled by the first driving member 132. The connecting sleeve 161 is made of rigid material and does not affect the volume change of the driving member 13 or the transmission of driving force.

[0061] The connecting sleeve 161 can adopt a telescopic structure to adapt to the radial movement stroke of the movable tube segment 12; the connection at both ends is treated with a seal to prevent mud and sand from seeping in.

[0062] The connecting sleeve 161 and the dowel bar 141 form a dual guide, which greatly improves the accuracy of the movement of the movable segment 12, reduces the stress on the dowel bar 141, and extends the service life of the force transmission structure. The guiding constraint ensures that the movable segment 12 always moves smoothly in the radial direction, ensuring tight contact with the concrete during support and smooth separation during demolding, further reducing disturbance to the wall joint and ensuring the forming quality and seepage prevention performance of the anti-seepage wall joint.

[0063] According to one embodiment of this application, such as Figures 1 to 3 As shown, the connector tube 1 also includes a reset member 162, which provides a reset force to bring the movable tube 12 toward the demolding state.

[0064] The reset component 162 can be installed between the movable segment 12 and the inner support cylinder 11, forming a collaborative working system with the first drive component 132 and the second drive component 135. In the supported state, the thrust generated by the expansion of the second drive component 135 overcomes the reset force of the reset component 162, pushing the movable segment 12 against the concrete; in the demolding state, the second drive component 135 depressurizes and contracts, and the reset component 162 releases its reset force, assisting the first drive component 132 in pulling the movable segment 12 radially inward, tending towards the demolding state. The reset component 162 is positioned to avoid the force transmission rod 141 and the connecting sleeve 161, so as not to interfere with the normal operation of the guide structure, further enhancing the stability and timeliness of the movement of the movable segment 12.

[0065] The reset element 162 can be a tension spring, which can be set in 2 groups along the circumferential direction of the inner support cylinder 11 and in 3 groups along the axial direction of the inner support cylinder 11, that is, the total number of tension springs can be 6.

[0066] The reset element 162 provides a stable reset force, assisting the first drive element 132 in pulling the movable segment 12, reducing the dynamic load on the first drive element 132, and improving demolding efficiency. In the supported state, the reverse force of the reset element 162 can offset some of the fluctuations in the concrete side pressure, preventing small displacements of the movable segment 12 and ensuring joint forming accuracy. During demolding, the reset force can quickly cause the movable segment 12 to contract, shortening the contact time with the concrete, reducing disturbance to the wall joint, and preventing the movable segment 12 from failing to reset due to jamming, thus improving the consistency and reliability of the action.

[0067] According to one embodiment of this application, such as Figure 3 As shown, along the height direction of the connector pipe 1, one end of the inner support cylinder 11 is provided with a socket 111, and the other end is provided with a spigot 112. Adjacent connector pipes 1 are fitted together through the socket 111 and the spigot 112.

[0068] The inner support cylinder 11 achieves axial docking of adjacent joint pipes 1 through the concave-convex fit of the socket 111 and the spigot 112, which can quickly complete the positioning and assembly of the joint pipes 1, ensure that multiple joint pipes 1 are arranged coaxially along the height direction, avoid offset or tilting after connection, and ensure that the cylindrical shape formed by the entire joint pipe assembly is regular, providing a stable structural foundation for supporting concrete and subsequent joint hole forming.

[0069] The setting of the fixing pin 113 further enhances the connection reliability of adjacent joint pipes 1, prevents relative displacement of joint pipes 1 due to vibration, impact or concrete lateral pressure during construction, and ensures the sealing and structural integrity of the connection. Figure 2 The diagram shows the insertion position of the fixing pin 113 (no actual component is added for clarity).

[0070] When the horizontal stripping anti-seepage wall joint pipe assembly provided in this application embodiment is used after assembly: The main water bladder (second driving component 135) inflates with water, driving the semi-circular movable tube segment 12 to a predetermined position. The demolding spring (reset component 162) stretches from its natural state to a taut state, while simultaneously the demolding water bladder (first driving component 132) deflates and shrinks to a deflated state. The movable tube segment 12 of the connector pipe 1 is placed into the trench with one side facing the concrete to be poured, and concrete pouring begins. Once the concrete has initially set, the connector pipe assembly remains stationary. The main water bladder deflates and shrinks, and the taut demolding spring pulls the movable tube segment 12, causing it to move horizontally along the sleeve and detach from the concrete, creating a gap for demolding. Figure 3 The gap between the left boundary of the concrete (dashed arc) and the movable segment 12 is the demolding gap. When the setting force is too large and the demolding spring tension is insufficient to pull the segment out of the mold, the demolding force is increased by filling the demolding water bladder with water. For the lower part of the concrete that has completed its initial setting, the movable component of the joint pipe 1 begins to move horizontally to demold, while the upper part of the concrete that has not completed its initial setting continues to be poured rapidly, achieving demolding while pouring. In this embodiment, the horizontal demolding joint pipe 1 driven by the water bladder is used. The contraction and expansion of the water bladder drives the segment to move horizontally and detach from the initially set concrete. On the other hand, during the wall pouring process, the changes in the concrete setting process are detected by monitoring the pressure changes in the water bladder to determine the concrete setting state, the concrete pressure on the pipe wall, and other key parameters, and to determine the demolding timing of the joint pipe 1; the horizontal displacement of the water bladder due to expansion and contraction is determined by monitoring the pressure and liquid injection volume of the water bladder to further monitor the horizontal demolding distance of the movable segment 12 and control the demolding process. Using this connector pipe 1, a circular joint can be formed at the joint of adjacent groove sections, so that each section of connector pipe 1 can be pulled out horizontally from bottom to top, which greatly reduces the difficulty of pulling out connector pipe 1 and avoids pipe casting accidents.

[0071] like Figure 5As shown, the greater the water volume of the first driving member 132 and the second driving member 135, the greater their volume expansion, that is, the greater the displacement of the driving member. Figure 6 As shown, after pressurized liquid is injected into the second driving component, a certain pressure is maintained to keep the movable segment 12 in a supported state; as the amount of concrete poured increases, the lateral pressure of the concrete on the joint pipe wall also gradually increases (limited to...). Figure 7 (The part to the left of the highest point in the middle), at this time, the water pressure in the second drive component should be gradually increased to match the gradually increasing side pressure of the concrete, so as to avoid the excessive pressure of the concrete causing the movable segment 12 to retract slightly.

[0072] Furthermore, the horizontal demolding anti-seepage wall joint pipe assembly provided in this application embodiment can be reset at any time after demolding. The reset pipe segments can support the concrete and protect the joint, thus accelerating the concrete pouring speed and improving construction efficiency. In addition, the reset pipe segments can isolate the mud from the concrete, preventing mud skin from adhering to the concrete joint and improving the quality of the concrete joint. Monitoring data such as water pressure and demolding stroke during the pouring process provide an optimization basis for subsequent key construction procedures such as wall pouring speed control, trench wall stability, and demolding timing.

[0073] According to a second aspect of this application, a joint pipe operation and monitoring system includes the aforementioned horizontal de-mode seepage barrier wall joint pipe assembly, a water tank 2, and a control and monitoring device; wherein, the water tank 2 is connected to the receiving cavity 131 of the drive member 13 to provide pressurized liquid; the control and monitoring device controls the amount of pressurized liquid injected into the drive member 13 and acquires the pressure data within the drive member 13.

[0074] like Figure 4 As shown, water tank 2 is connected to inlet pipe 21 and outlet pipe 22. Water tank 2 can also be in the form of a water storage tank.

[0075] like Figure 4 As shown, the control and monitoring device 3 includes a demolding control parameter display 31, a device control button 32, a monitoring parameter display screen 33, an interface integration 34 for the first drive component (each section of the connector pipe has a first connecting pipe connected to an interface), an interface integration 35 for the second drive component (each section of the connector pipe has a second connecting pipe connected to an interface), an indicator light 36, and a power external interface 37; and is connected to the water inlet pipe 21 and the water outlet pipe 22 of the water tank 2.

[0076] The joint pipe operation and monitoring system integrates the horizontal demolding anti-seepage wall joint pipe assembly, water tank 2, and control and monitoring equipment to form an integrated operation system. Water tank 2 serves as the water supply unit, connected to the drive component 13's receiving cavity 131 via a high-pressure resistant pipeline. The control and monitoring equipment precisely adjusts the pressure liquid injection volume, changing the volume of the drive component 13. Simultaneously, the control and monitoring equipment acquires pressure data within the drive component 13, combines it with pressure sensor feedback to determine the concrete solidification state, and coordinates the actions of the first drive component 132, the second drive component 135, and the reset component 162 to achieve automated and precise control of the support and demolding processes.

[0077] A control valve can be added to the pipeline to work with control and monitoring equipment to achieve precise start and stop of the injection and drainage of the drive component 13. The control and monitoring equipment is connected to the internal fluid of the drive component 13 through the connecting pipeline to receive pressure data in real time.

[0078] The control and monitoring equipment precisely regulates the injection volume of pressurized liquid, ensuring that the supporting force and demolding force output by the drive component 13 match the concrete condition, thus improving operational stability. Real-time pressure data feedback allows for dynamic adjustment of drive parameters, which, in conjunction with the auxiliary function of the reset component 162, reduces the power load on the first drive component 132 and optimizes energy consumption. The integrated system control reduces manual intervention and operational difficulty, while ensuring joint forming accuracy during support and minimizing wall disturbance during demolding, thereby improving the overall quality and efficiency of the anti-seepage wall construction.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
